VULCANIZED PAINT.

T0 :LZZ w/mm it may concern.-

Be it known that l, LUKE W. ()sBoRx, a citizen of the Inited States, residing at Joliet, in the county of Will and State of Illinois, have invented certain new and useful Iniprovcmeiits in Vulcanized Paints, which is fully set forth in the following specification.

My invention relates to the production of a paint which shall provide an elastic pliable coating for roofs and other locations where such a paint is desirable.

The invention coiisistsin a paint composed of g un ti irpen ti gjggseed-inp gilage, and linseed-oil heated and then vulcanized with su iur.

ii preparing this paint I employ the crude g 0 the pine-tree, known in commerce as inn-U11 entine," and to any certain quantity oithe same I add about five per cent, by weight, of linseed-oil for the purpose of properly soften'iig IO gum. The quantity required will vary somewhat according to the state of the gum. If it is very hard, more oil will be required, while if already soft less should be used, the oil in any case being added in quantity sufficient to make the gum quite soft and plastic. The gum and oil added thereto are heated to about 225 to 230 Fahrenheit, or the gum may first be melted by the application of about this degree of heat and the oil then added. To this hot liquid I then add aboutfifty per cent, of liquid measurement, of a quite thick stilt fiaxseed-mucila e. straining flaxseed. The ingredients are well m xed together and kept at about the temperature mentioned above, and there is then added to the hot mixed liquids about fifteen to twenty per cent, by weight, of siil hur, this being the average quantity of suiphi'ir required to vulcanize the mass. The quantity of sulphur demanded will, however, vary somewhat, according to the condition of the gum, and in all instances it must be sutficient to thoroughly vulcauize the liquid compound. I also prefer to add to the compound a small quantity of silicate of sodasay in about the proportion oi two ounces thereof to a gallon of the paint. This silicate of soda This mucilage I prepare by Boii'iu'g and acts as a drier to harden the paint,and is sometimes desirable, though I do not make it an essentialingredient. The addition of the mucilage to the gum produces a mixture which when vulcanized is pliable, elastic, and tough. The result of the process above is a liquid somewhat similar to a hydrocarbon treated with sulphur. The liquid, when spread and allowed to cool and harden, forms a thin sheet or film which is quite pliable and elastic and is suitable for use as a paint where these properties are desirable. The paint mustbe applied hot and may he used without any substance added or with some additional material, for the purpose, however, of finish only. For instance, in coating roofs and sides of buildings, either brick or wood, I sometimes add crushed specular hematite ore white sand, or anv other like material tiat will improve the appearance of the surface when finished.

This painthardeus as it cools, but is sufiiciently pliable and elastic to withstand the changes due to contraction and expansion under changes in temperature, so that it provides a very durable and satisfactory paint. It is sufiiciently elastic to stand the bending of a surface to which it is applied-tin, for instance, or other sheet metal-so that it may be applied not only to articles made of such material, but even to the sheets of metal before bending.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The herein-described paint, composed of gum-turpentine, linseed-oil, flaxseed-inucilage, and sulphur, in about the proportions specified, and thoroughly vulcanized, substantially as described.

2. A paint composed of gum-turpentine, linseed-oil, fiaxseed-mucilage,silicate of soda, and sulphur, in about the proportions specified, and vulcanized by the application of heat, substantially as specified.
